Application filed January 31, 1914. Serial No. 815,763.

lie it known that `I.l `uununien TW. Senna, Jr.. a rilizeu of the United States. residing :it ffhii'fago. in the county of Cook and Stato ot' illinois, have invented a new and useful improvement in Coheilyens. o'whieh the ."ohiwing is a specification.

ily in vention relates to an improvement in the ela of Coke-ovens in 1which the Aove-n Hierin-im; a battery of retorts, each retort being' between parallel series of vertieal heating' fines and the battery surinonnting res nerative elian'ibers. through which the hot ses are passed in periodiaally reversed di- Afeetion for adapting the chambers to heat the air used 'for the Combustion.

in the use of a coke-oven of the kind referred to5 free carbon deposits in the fuelfmssages. elogging the-1n and inipairing the oven and its operation; and the primary object oi? my invention is to provide automatieally-nyerating nieans for burning out this A bly with each reversal.l re- ''mred to, these. reversals being ordinarily produced at half-linnn intervals, or thereabont. f

eolie-oven battery of the kind to which my improvement is applied comprises the 'toi ion-ine" nelierally-described construction.: ff.hocker-ehambers 9 and l0, separated by a diiiding-wall lll, are built on a substantial Vtmuulation i9, and each communicates through ar base-opening;` 13, by means of a T-(wunling ll eonneeting it with an elbow l5, with a lateral flue llt extending in. the 'lnnidation lengthwise. of the battery and eoniniunicating through branches, as indicated at 17 in Fig. 2, with a Vcentral stackflue 18. Surinounting;r the chambers 9 and l() is a battery oi retorts lf), closed by removable end-doors Q0 and ol which any desired 60 number may be provided. The particular battery for which my improvement has been designed contains more than sixty of these retorts. Each retortis between walls 2l containing longitudinal series of vertical heating dues 22 rising from a base containing upwardly-tapering nozzles 23, one at the bottom of each fine; and each due contains a short' air -tube 24; to one side and rising above the nozzle to take the heated air through an openin Q5 in said base and mix it at an elevation aoove the respective nozzle with the gas that is introduced into the line. Each row of flues 22 has extending underneath it in` the aforesaid base., a gas-passage 2G. from which the nozzles 23 are fed, this passage being closed at each end by a species of nozzle known in the art as a gun` 27. ri'he lues 22'in eac-h row discharge at their upper ends into a horizontal passage 29 in a superstructiue containing a horizontal passage 28 communicating with the passage 29 thro-ugh opening 29a lining` with the lues S22 and cap-covered lines 30 extending with the openings 29a.

rihe gas for heating the ovens cornes from two inains 31, 31 extending along opposite sides of the structure. These mains are opened alternately into the guns to the opposite ends of the passages 26, and each time one main is thus opened, communication of the opposite niain with the guns on that side is closed. ln thus openin` one inain a slide-valve 14' below itis opened to admit air into the adjacent checker-Chamber, and at the same time a similar' valve lll2 in the lower end of the same coupling-hand is closed. il/Vhen the les ing upwardly from the passage' and alinas 27 leading a0 in the top of .the head of each coupling- 'l-l immediately effecting 35 at the front end 11o s a as fue through Ehe amiss 1s corressomimg ufes 22, with 5G ind-gas; andfolowng is a des'pton of the for the purpose lus'matsd fhe lsfsrrng to Figs. 3 and 5 a pipe ing from like main 3L terminates ai; its
